Hey guys so still trying to get my fb running well, engine is out of 79 (body is an 83). I have a Weber 48 ida so obviously cold starts are tough I also have a duralast gold (which is junk) planning on getting an xs power or something like that, but anyway I drove it to a storage unit that my friend has so we could work on it, heated on the inside and whatnot and I went to move it and I couldn’t get it to start it would just crank so I assumed it was flooded. I did the deflood procedure with atf fluid and took a while to start but eventually did , so it ran for about 5-10 minutes and stalled. while it was idling I didn’t notice any jumps in the in the rpm or anything until it was about to stall. I started it again and same thing i need to get a new fuel pressure gauge jegs are junk
Im trying to upgrade the things that will help start ups so I was wondering if I should upgrade ignition coils to msd? My uncle thinks I have a vacuum leak but i wasn’t sure since it will idle fine just until it’s about to die I do need to set the timing still it’s just at TDC with the distributor (83) lined up. Spark plugs usually look fine I’ll just have to wipe them off if it’s flooded. I have a brand new alternator from a s4 and a new starter as well. Want to throw money at the suspension but ya know should probably make sure it runs first :-P I will be open to any suggestions and any advice I can get thank you guys
Are you getting icing in the carb due to the cold weather? I used to get that on my Dellorto until it was really good and hot if it was below 30F outside. You probably just need to babysit it better until its good and warmed up or drive it around some. At idle, even hot it may still ice up if conditions are right and the air isn't moving very much (idle).
For good starts you need a very good battery, a starter that spins at the proper rpms (faster better) and a good ignition. For ignition I would go with a modern solid coil and a DLIDFIS setup to get the best spark possible without resorting to ignition boxes like MSDs (which are kind of over rated IMHO).

thats the thing is I had it in my buddy’s storage unit which is at about 65 degrees inside it’s heated, and I didn’t think I’d have any problems getting it started because it was warm in there and I’ll definitely check into the DLIDFIS, I wasn’t sure if I should go with an optima battery or not i read somewhere on here to go with something that has like 900+ cold cranking amps the gold I had was like 700 and was junk

A 24F battery is the normal size to get (in Exide terms I think). The key is to make sure its always fully charged and that your alternator is recharging it even at idle. You maybe had a bad battery or it wasn't getting a good charge. Rotaries are very sensitive to cranking speed, especially as they age. I get my batteries at Wllay mart every 4 or so years, they don't last much longer than that.
Just went through something similar. Ended up cleaning all the battery cable connections and swapped a couple of cables while relocating the battery. That seemed to help a little, but wasn't the final answer. I ended up swapping the starter with another newer one I had sitting around and the engine turned over much faster. It started right up (and still does). I just bought a rebuilt second gen automatic tranny starter that has the 2kw motor. Am going to swap the 2kw motor onto the nose piece of the old dying starter that I just removed. That may be overkill, but more reliable is better when endurance racing. Nothing worse than racing for 2 hours straight, then having to push start the car after the next driver gets in.
Answering your post made me get out of my seat and check the new 2nd gen starter I got. Looks like the swap is not going to be as simple as I thought. The diameter of the motors is different. I may have to find a junk 2nd gen 1.2kw starter and use that nose piece. I will let you know.

thank you for the feed back! I was thinking about upgrading that as well let me know how it goes!
try starting fluid spray check battery fuses clogged fuel filter can also be it old gas can be all the above my car sat for 5 years and I had all these happen oh and loose cables
Transplanted the 2kw motor from an FC auto tranny starter onto the nose of an FC manual tranny starter. Fit together really easily. Bolts into my FB no problem and works fine. Because of the different drive mechanism it sounds way different than the stock FB starter. As others have said it sounds like a turbine. For various reasons I have not been able to do a good comparison on cranking speeds with the stock and 2kW starters, but should get around to it next week. I will let you know the results.
Personally, & I mean this... everyone has a different opinion....especially upon batteries.... however, I love those blue tops.... worth every penny... last one in my '98 Chevy C1500 lasted over 8 years... & I was running a 1000watt stereo system too!

You should put up a thread on how this is done. Sounds interesting.

dang! Okay so do you think I should try and get one with like 800+ cca?? And I was heavily looking into that fc 2kw starter mod

so I was actually thinking about doing this but I wasn’t sure if I could use the fc auto starter so this is awesome I definitely think this will be a huge help for starts and stuff!

I check the fuel filter I think that’s the one thing I haven’t really looked over
This video shows exactly what is needed. The only difference is that in the video they are transplanting an Rx8 starter motor onto an FD nose. For application to the FB (or SA or FC) you need the starter nose from a manual transmission FC starter and the motor from an automatic transmission FC starter. Then follow the instructions in the video. If you are working with used parts, the other video shows how to refurbish your used parts.
It was surprisingly easy once I dove into it. I was working with a reman auto tranny starter from RockAuto and a bunch of gummed up parts from a manual starter.
